WILLIAM LIVINGSTON DENIO, OF ROCHESTER, NEW YORK, ASSIGNOR OF ONE-HALF TO HOBART F. ATKINSON, OF ROCHESTER, YORK.

MANUAL AND AUTOMATIC CIRCUIT-CONTROLLER.

SPECIFICATION forming part of Letters Patent N0. 761,454, dated May 31, 1904;.

' Application filed January 20, 1904. Serial No. 189,924. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM LIVINGSTON DENIO, a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Manual and Automatic Circuit-Controllers; and I do hereby declare the following to be a full, clear, and exact description of the invention,- such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improved apparatus for sending either manual or automatic fire-alarm signals in the general manner described in my Patent No. 397,838, dated February 12, 1889.

The main object of the invention is to provide a simple and eflicient circuit-controller adapted to serve as a manual push-button and also as an automatic signal device operated thermostatically, also to provide such device with improved means for showing at the sending-station the transmission of the signal.

In the accompanying drawings, Figure 1 is a front View, and Fig. 2 a rear view, of the device. Fig.3 is a sectional view on line 3 3 of Fig. 2. Fig. 1 is a partial front view with the cover of the push removed, and Fig. 5 is a small diagram.

Numeral 1 indicates a back plate having circular opening 2, over which is secured a body 3, which has a central extension at, onto which is secured the cap 5, which has a central perforation to receive the end 6 of the push 7 and the two reverse overlapping cuplike parts 8 9, between the bottoms of which is a coiled spring 10. Parts 8 9 are normally held together, as shown, by a fusible solder or material, (as common in similar devices,) whereby spring 10 is held under tension and cannot operate push 7 The outer part 8, which forms the fbutton, ,at its inner end has outwardly-extending lugs or parts 11, which project under the periphery of the opening in cap 5, preventing further outward movement of the cap, but permitting movement inward. Push 7 has a groove. or depression 12 normally on the outer side of the spring-arm 13 on the face of the extension 1, which presses against part 7 but which when 1 part 7 is pushed in falls into groove 12 and holds part 7 in. The bottom of part 9 bears against the shoulder at the base of the reduced end of part 7 l4: indicates a spring in the base of body 3, one end of which spring is secured to the rear face of said body and the opposite end of whichis' secured to the base of push 7, throwing the push out to the position shown in Fig. 3.

In the outer face of extension 4 is a contactplate 15, on which spring-arm 13 normally rests.

15 indicates another contactplate, onto which arm 13 moves when it falls into groove 12, as shown by dotted lines in Fig. 4.

In the hollow base is a ring-shaped resistance device 20, consisting of a suitable resistance-core 21, of wire or other suitable material, with a protective winding and an exterior binding thread or wire 22 thereon. This resistance forms a protecting-shunt to the signal-lamp and is made in the form shown to fit in the case, where it is easily and securely held and does not require a special holder. On the base is also mounted a signal-lamp 21, inclosed by a cap of metal (or other strong material) 22, which has several small perforations 23, serving to emit sufficient light when a signal is being sent to show that the signal is actually transmitted. This is safer than aglass cap and is fully as efiicient.

The apparatus above described is designed particularly, but not exclusively, for use in an auxiliary fire-alarm systemsuch, for example, as shown in my application, Serial No. 156,538, dated May 11, 1903. Such auxiliary system employs two line-wires 1 1 between a central oflice, where the source of current is located, and a manual and automatic circuitcontroller and the auxiliary box and a third wire between said circuit-controller and said box.

In the normal condition one side of circuit 1 1, extending from the central station to the building at which an auxiliary signal-box is used, as described in my application above referred'to, connects with arm 13 of the signal and automatic device resting on contact and onto line 1 again. When the manual device is operated, part 13 moves onto 15 to said side of line 1 1 through lamp 21 to auxiliary wire 3.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a manual circuit controller, the grooved push, the spring adapted to enter the groove when the push is operated, and a second spring normally holding the push forward.

2. In a manual circuit controller, the grooved push, the spring adapted to enter the groove when the push is operated, a second spring normally holding the push forward, and the push-button with reverse cup parts adapted to be separated by heat, and an intermediate spring.

3. In a manual circuit controller, the grooved push, the spring adapted to enter the groove when the push is operated, the second spring normally holding the push forward, and the push-button with reverse cup parts adapted to be separated by heat, an intermediate spring, and the spring behind the push.

4:. In a circuit-controller, the body 3, circuit-contacts and a switch-arm supported on body 3, the grooved push, said switch-arm being adapted to enter the groove in the push when the latter is operated, which entering movement carries the switch-arm from one contact to another, a second spring normally holding the push in position to be operated, and a resistance device supported back of body 3.

5. In a circuit-controller, the back plate, body 3 on said plate, a push extending through body 3, a spring normally holding the push in its operative position, a circuit-changing arm brought into action by movement of the push, contacts with which the arm cooperates, and the resistance supported in a space back of body 3 and connected to the contact to which the arm moves when the controller is operated.

6. In a circuit-controller, the body 3, circuit-contacts and a switch-arm supported on body 3, the grooved push, said switch-arm being adapted to enter the groove in the push when the latter is operated, which entering movement carries the switch-arm from one contact to another, asecond spring normally holding the push in position to be operated, and a button for the push having parts held together by fusible material, a spring between said parts which spring when the fusible hmaterial melts is adapted to operate the pus In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

WILLIAM LIVINGSTON DENIO.
